Cool, so emachisit and what wheel sizes, wheelbase, gear ratios etc. are available?

AU$99.95 and don't have the foggiest on the guts of it because they don't come in 14mm gauge so are of no use to me! But then neither do yours that i am aware of...:sad:

That's not a bad price.

My mechanisms are available in gauges from 9mm up to about 25mm, but do not fit under-the-floor like the others you mentioned. As Bergs are probably most interested in powering their suburban cars with the Stanton Drive, my units would not be suitable anyway.

However, none of the under-the-floor types are offered in less than 16.5mm gauge, and only the Black Beetle is offered in gauges from 16.5mm up to 32mm.

My name has come up a few times in this forum, so I've just joined to help out with some of the questions. Yes, I designed the Stanton Drive and it's now in production by Northwest Short Lines, replacing their PDT product. (http://www.nwsl.com).

It's a digression from where this thread started, which was battery powered, radio controlled HO scale models; specifically an application in Sydney suburban electric multiple units. The articles in the Australian Model Railway Magazine are continuing and will provide reasonably complete explanation, although I know some readers are getting inpatient. The articles have been written for some time and publication depends on space allocation and layout of the magazine.

Just a word on batteries. I'm using a single cell lithium polymer battery, 750 mAH (3/4 of an amp-hour) capacity. Remember, I'm working in HO with motors that have a stall current less than 250 mA. Typical running current is 100 mA at 12 volts, and, yes, I am using a step-up converter to get 12 volts. Charging current is limited at 500 mA and charging only occurs in stations and on storage sidings. The rest of the layout has no track wiring. I haven't welded any wheels to rails yet, and don't expect to.

G'day Neil,
 Glad you found the forum-it was me you spoke to on the phone today.
Hope I described your system accurately!

Neil does this system have enough power to run the locos with a sound decoder installed?

That and removing the battery to recharge are the main things holding me back from going to the dark side.

I always liked the idea of a side track where the loco could be recharged through the rails.:2t:

Welcome to Freerails!

How about describing the "step up converter" circuit?

Sounds like a great system to me. I would like to know how long a charge lasts under "typical" operating conditions.

Hi Mark, Dave and Herb,

First, the step-up converter: I originally bought converters from BetaDyne (http://www.beta-dyne.com) but the price kept increasing, so now I build my own. Being new to this forum, I'm not sure how much detail is appropriate or the best way to describe the design. Herb, can you give a little advice how best to respond to your request.

Re sound: Someone needs to tell me the power consumption of the sound system. Once I know power consumption, the rest of the battery issue is arithmetic to determine appropriate battery size and operating duration before needing a recharge. I'll do the math and explain the process, if someone provides the sound system data.

However, my concern with on-board sound is the choice of decoder. Remember, my goal is to operate with on-board battery power and radio control. No operational dependency on track wiring; "Free Rails" at last!. My radio control is NMRA standards compliant, which allows 2 options for a decoder; "kit-bashing a commercial DCC decoder card or building my own decoder. I've done both and prefer my own decoder for loco operations (not too surprising).

I have not investigated sound decoders, but I certainly will not attempt building my own. That means converting loco control/sound decoders for battery power and radio control. To my knowledge, this is unknown territory.

Hi Woodie,

With the 750 mAh battery and no recharging, I get 2 to 3 hours operation with the Sydney suburban electric multiple units (one motor per 4-car set). For heavier locos and trains in HO scale, I would use a larger-capacity battery.

For O-scale and larger, I would use a 3 or 4-cell lithium-polymer battery pack; probably with an external battery charger.
